[Children's respiratory health and air pollution].

Two surveys--one in children 9-11 living in an industrially polluted area, the other one on younger children in an urban environment--combined the collect of previous health impairments through a standardized questionnaire, clinical examination and respiratory functional testing with automatized air pollution measurement. Results confirmed those of similar surveys, that is the mildness of observed anomalies and the diverging perturbations: clinical symptoms without functional alterations or the reverse. Complementary research is therefore needed, if possible longitudinal.
